Black Ops Sells 18m Map Packs

This translates into an average expense of $76 per customer who purchased Black Ops, according to Eurogamer. Obviously not every consumer has actually purchased the map packs, but several -- including many IGN editors -- have bought all three that have released since last November.

Black Ops' number is also significant because it shows that the DLC is still trending upwards with each iteration on the franchise. During the same amount of time, World at War sold 9 million units of DLC, while Modern Warfare 2 sold 11 million. Could the next title, Modern Warfare 3 break the new record and continue the streak?

Activision surely hopes so. In their same analyst meeting where the company disclosed the Black Ops DLC figures, execs also reported that revenues from digital sales hit 1.7 billion dollars this last year.

Do you buy all the DLC when it comes out? As much as gamers slander Call of Duty as a franchise in the comments, you'd think no one enjoys it. But the sales figures -- and more so the money -- say otherwise.
